The newborn vision is not as clear as in adult. The development of vision will become gradually clearer by the age of 4 to 5 years. The visual behaviors of children of each age range can be described as follows.
Amblyopia (Lazy eye) is the loss of the ability to see clearly through one eye and can occur of over/under using it. The eyes are like any other organs and will deteriorate due to lack of usage and may eventually lead to blindness.
Amblyopia (lazy eye) can be treated by encouraging children to use their eye side with affected with those vision problems. The ophthalmologist may place a patch on the good eye and/or use eye drops in order to dim the eyesight, thus enabling the children to use the lazy eye. This will help to increase the recovery and improve the eyesight more effectively. The eye closure should be done at an early age because the treatment will be more complicated, and the results will be seen increasingly slower when they are older. Especially with the children at 9 years of age, results for recovery may not be as positive.
